It is not uncommon to see red and orange, especially in slower fireballs.
While the meteor is still visible (and with a smoke trail) it is moving at
hypersonic velocity, miles up. If the body slows enough before it burns up,
what's left falls slowly, dropping generally below any terminal explosion,
or below the point where the meteor stops burning.

What the witnesses saw happened before it slowed down. Nothing would have
been visible for a few minutes after that, while (maybe) meteorites were
falling. Most people don't look up, so the meteors that are widely witnessed
are usually near the horizon. People think that they are landing nearby, but
of course they are far away, sometimes hundreds of miles. What you want to
find are witnesses who saw the fireball disappear right overhead. Then you
know you're in the right place to hunt for meteorites.
